It was sometimes possible to get high enough to experience this unpleasant condition. If in a turn, where the inside wing would be close to stalling and the outboard one to approach the Mach limit. I went up there once and didn’t like it, I was wearing the full kit of g suit, pressure jerkin and a Taylor Helmet with an Air ventilated suit which had bleed to an air ventilated skull cap worn inside the helmet. Beyond uncomfortable!
